error finishing read and joint following error.

******Dr. Emmit Brown***** "IT WORKS........IT WORKS! i finally invented something that works."

Greetings, i finally got a working configuration on my dell vostro desktop but I am getting error finishing read and then a joint 0 following error. even after i disabled all the virtualization options in bios and i did the irq balance according to this link forum.linuxcnc.org/38-general-linuxcnc-q...ead-and-irq-affinity .this is only an issue on this machine. it works perfectly on a duo core laptop but i can't get it stable on the the desktop. i did read a post that said if i update the rtkernel to something above 6.1 to something like 6.3 that it might fix that issue but i am unsure on how to do that exactly? Tried to compile a kernel according to the instructions on myheap.com but i keep getting a make error and i shouldn't have to compile a whole kernel just to update to a newer version do i? you guys on this site have been amazing already with helping me get this machine working and any help you can offer on this issue will be greatly appreciated.


I'm running a Dell Vosrto with an i5 3.4ghz cpu with dual intel Ethernet cards,  right now there is firepro gpu in it. i'm on linuxcnc 2.9.2 with 6.1.1 rtkernel.

Can you run this script to check the IRQ pinning and
kernel command line setting:

 

Also since you have Intel MACs, have you disabled IRQ coalescing?

(man hm2_eth)

 

i will run that script tomorrow when im in front of it. are you referring to the hardware coalescing in /etc/network/interfaces? (or something of like that) add that last line from (man hm2_eth) to that file?

hardware-irq-coalesce-rx-usecs 0 this line right here?

totay i can't ping the mesa board @ 10.10.10.10.
yesterday i could at least jog for a second

What does:

ip a

report?
 

should that i915 be there? i seem to remember reading something about that in this forum somewhere. this what i get in the error report, hm2_eth: rtapi_app_main: Connection refused (-111)
today i deleted the connection i created and configured the network frome the interfaces file.

source /etc/network/interfaces.d/*

# The loopback network interface
auto lo
iface lo inet loopback

# The Mesa 7i96s FPGA card interface
auto enp5s0
iface enp5s0 inet static
address 10.10.10.10
hardware-irq-coalesce-rx-usecs 0

You have the IP address of the host = the card IP address
This cannot work. I would suggest setting the host address
to 10.10.10.100

okay, did that, i can at least ping it and jog for one second and then get the same errors. error finishing read and joint 0 following error.
